From c4c87f2971c85eabe8e9bbfc98be21905818227a Mon Sep 17 00:00:00 2001 From: Guilherme Date: Wed, 30 Jul 2025 15:40:46 +0100 Subject: [PATCH] Making GetTextWidth part of the public API (#480) GetTextWidth is useuful to be called publicly. E.g: when you want to get the final horizontal size of a Slider that has textBefore and textAfter. --- src/raygui.h | 176 ++++++++++++++++++++++++++------------------------- 1 file changed, 89 insertions(+), 87 deletions(-) diff --git a/src/raygui.h b/src/raygui.h index 6011c17..4b02627 100644 --- a/src/raygui.h +++ b/src/raygui.h @@ -761,6 +761,9 @@ RAYGUIAPI int GuiColorBarAlpha(Rectangle bounds, const char *text, float *alpha) RAYGUIAPI int GuiColorBarHue(Rectangle bounds, const char *text, float *value); // Color Bar Hue control RAYGUIAPI int GuiColorPickerHSV(Rectangle bounds, const char *text, Vector3 *colorHsv); // Color Picker control that avoids conversion to RGB on each call (multiple color controls) RAYGUIAPI int GuiColorPanelHSV(Rectangle bounds, const char *text, Vector3 *colorHsv); // Color Panel control that updates Hue-Saturation-Value color value, used by GuiColorPickerHSV() + +// Util +RAYGUIAPI int GuiGetTextWidth(const char *text); // Gui get text width using gui font and style //---------------------------------------------------------------------------------------------------------- #if !defined(RAYGUI_NO_ICONS) @@ -1495,7 +1498,6 @@ static void DrawRectangleGradientV(int posX, int posY, int width, int height, Co //---------------------------------------------------------------------------------- static void GuiLoadStyleFromMemory(const unsigned char *fileData, int dataSize); // Load style from memory (binary only) -static int GetTextWidth(const char *text); // Gui get text width using gui font and style static Rectangle GetTextBounds(int control, Rectangle bounds); // Get text bounds considering control bounds static const char *GetTextIcon(const char *text, int *iconId); // Get text icon if provided and move text cursor @@ -1687,7 +1689,7 @@ int GuiLine(Rectangle bounds, const char *text) else { Rectangle textBounds = { 0 }; - textBounds.width = (float)GetTextWidth(text) + 2; + textBounds.width = (float)GuiGetTextWidth(text) + 2; textBounds.height = bounds.height; textBounds.x = bounds.x + RAYGUI_LINE_MARGIN_TEXT; textBounds.y = bounds.y; @@ -2027,7 +2029,7 @@ int GuiLabelButton(Rectangle bounds, const char *text) bool pressed = false; // NOTE: We force bounds.width to be all text - float textWidth = (float)GetTextWidth(text); + float textWidth = (float)GuiGetTextWidth(text); if ((bounds.width - 2*GuiGetStyle(LABEL, BORDER_WIDTH) - 2*GuiGetStyle(LABEL, TEXT_PADDING)) < textWidth) bounds.width = textWidth + 2*GuiGetStyle(LABEL, BORDER_WIDTH) + 2*GuiGetStyle(LABEL, TEXT_PADDING) + 2; // Update control @@ -2214,7 +2216,7 @@ int GuiToggleSlider(Rectangle bounds, const char *text, int *active) if (text != NULL) { Rectangle textBounds = { 0 }; - textBounds.width = (float)GetTextWidth(text); + textBounds.width = (float)GuiGetTextWidth(text); textBounds.height = (float)GuiGetStyle(DEFAULT, TEXT_SIZE); textBounds.x = slider.x + slider.width/2 - textBounds.width/2; textBounds.y = bounds.y + bounds.height/2 - GuiGetStyle(DEFAULT, TEXT_SIZE)/2; @@ -2239,7 +2241,7 @@ int GuiCheckBox(Rectangle bounds, const char *text, bool *checked) if (text != NULL) { - textBounds.width = (float)GetTextWidth(text) + 2; + textBounds.width = (float)GuiGetTextWidth(text) + 2; textBounds.height = (float)GuiGetStyle(DEFAULT, TEXT_SIZE); textBounds.x = bounds.x + bounds.width + GuiGetStyle(CHECKBOX, TEXT_PADDING); textBounds.y = bounds.y + bounds.height/2 - GuiGetStyle(DEFAULT, TEXT_SIZE)/2; @@ -2508,7 +2510,7 @@ int GuiTextBox(Rectangle bounds, char *text, int textSize, bool editMode) int textLength = (text != NULL)?
